Application filed October 7, 1912. Serial No. 724.473.

Toall whom it may 0071001 21:

ie itknown that I, i\NI)l".R li-rrnu Annunsnx, a subject oi? the King ot' Denmark, residing at Akrcn, in the. county of Summit and State of Ohio, have invented certain new and useful Improvements in Indicators; and I do declare the exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to indicators and more especially adapted to be attached to and form a part of a fluid containing tank of conventional design.

The primary object of the invention is in the provision of an apparatus of the character described, whereby the amount of the fluid contained within the tank or other rearrangement of parts as ceptacle is conspicuously and accurately indicated.

A further object of the invention is in the particular construction and arrangement of parts whereby the same are. rendered sensitive and capable of being accurately operated by the various elevations of the fluid in the tank.

With these and other objects in view, the invention consists of certain novel fPtllltl'GS of construction, and the combination and will be more fully described and claimed.

In the accompanying drawings; Figure l is a verti at longitudinal section of the complete invention showing the same attached to a tank; Fig. 2 is a side elevation of the operating i'i'iechanism of the-device, the. float thereof and guides carried thereby being in section; Fig. is a top plan view of the indicator; Fig. 4 is a cross section taken on the line at d of Fig. 1; Fig. 5 is a similar section taken on the line a e of Fig. 1; Pg. (5 is a plan View of a i'noditication ot' the metallic guide which is carried by the float.

In the lustrated embodiment of the invention 1 represents a tank of any well known construction and capable of containing a suitable fluid such as gasolene or other similar liquid.

The invention consists of a cylinder 2 which may be rigidly secured to or detachably fixed to the top of the tank and depends therefrom, the lower open end of which is positioned a suitable distance from tollowing to be the bottom ol the tank whereby the gasolene or other liquid may freely enter the cylinder. provided with an annular llauge 2-} which is in binding ccutact with the top of the tank and hern'icticaily scaled thereto, and rigidly attached to aid flange is an internally screw threaded collar "i: which forms the projecting and exposed gnd of the cylinder or indicator above the top of the tank.- The collar t is provided with an annular flange 5 forming the scat t r a gasket (1. and disposed upon the latter is a dial plate 7 which is sealed and properly secured by a gasket 8 and externally screw ,threaded ring 9 which is brought in contact with the gasket 5; whereby the dial is held in a seated and rigid position.

only bindingly holds the dial in a rigid 'po sition but it also secures in position a glass or lens .10 which covers the dial and upper gasket. 8 providing a suitable space between said lens and dial tor the free movement or rotation of a pointer 11 which cooperates with suitable graduations properly numbered or other identifying characters. whereby the amount of liquid contained within the tank can be. readily ascertained.

To the dial plate 7 and depending therefrom is secured a guide post or rod 12 which is substantially V-shaped in cross section and to the lower end of said rod is rigidly secured a plate 13 the opposite sides of which conform to the inner surface of the cylinder 3 but is sutliciently cut away or reduced as shown in Fig. 5 to permit the tree passage of the fluid into said cylinder.

In order to carry out the practical operation of the apparatus a shaft 14 is provided which consists of a strip of flexible metal or other suitable material twisted along its entire length and having its lower end removably mounted in an outstanding lu; 15 located adjacent to the plate 13, theupper end of said shaft loosely passing"v through the indicating dial 7 and to which is secured the pointer 11 for the purpose previously described. The float 15 is composed of suitable material and well adapted for the purpose, the ame being of a suflicicnt size to freely move within the cylinder 2 and capable of being operated by the height of liquid contained Within the tank 2. The

the rod 12 is provided with an opening Th upper cud ot' the cylinder The detachable ring 5) not which is slidably mounted upon.

' As shown in,

'yiclding extension 18 in which is fixed a frictional collar 16 which loosely eml'n'uccs said rod and conforms substantially to the shape of the latter, and secured to the upper surface of the float is a, plate l7 having an elongated opening formed therein through. which the shaft Lil it'rcely passes, said shatt and slot being so proportioned as to cause the latter to he turned. during the movement of the float. ln Fig. 6 a slight modification is shown whereby tie metallic guide plate for the shaft and the guide rod is formed of a single piece of metal with a projecting from one side of the plate 19 through which. the shaft passes and having its opposite free end out oficontact with the plate, whereby when the proper opening is formed in the float and the plate thus constructed is forced into said opening, the same will be held in a rigid and operative position with respect to the rod and s raft in parallel rclz im thereto.

lilg. 2 the platwhich engages with thesha't't lei is ecur d in position by uttliching lugs .20 which form an integral part thereof and hent downwardly, and forced into the material of which the float is composed. leurly shown the spiral shaft thus consrncel. is flexible throughout its entire lengt'hnnd therefore rendered very sensitive under the action of the various lieig the liquid contained in the tank, and furnier it is to he noted in this connection that said shaft is embraced by the li shaped rod 1 along: its entire length and partially housed thereby, whereby the float is centrally positioned within the chamber 2 andlui her any foreign accumulation or sediment that might adhere to the shaft will be removed there" from during the operation of said shaft by the outer ex osed ed es of the roll. lily the p n t particular formation of the collar in the guide post with which it engages the lloat 15 is prevented from rotating when the same is raised and lowered by the fluid con tained within the tank or receptacle -l.. It is further to be noted that the lower end 01"" the flexible shaft 14 can be readily detached whereby the same can he removed from the ll-shaped guide rod 1 1 for cleaning either the rod or the shaft which is very essential in devices of this character in order. that the. pointer may accurately indicate the various heights of the liquid contained within the tank.

The upper portion of the cylinder 2 is provided. with a plurality openings 21 located immediately below the top c" the tank 1, whereby the float is not retarded in incense its action by the action of air or liquid contained within the receptacle.

1* rom the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explanatioh.

I claim is tached to said tank, an indicatin dial secured to the upper portion of sai and exposed to'view, a guide post secured to the dial and depending therefrom, a plate secured to the lower end of said post, an out tending lug secured to the plate and provided with an opening, a shaft composed of a strip' of flexible material and twisted 1. An indicator for liquid containing. tanks comprising a cylinder removably atcylinder along its entire length and arranged adjacent to the post, the latter being substantially Vshaped in cross section, a float slid ably mounted upon the post within the cylinder and prevented from rotating by the some upon which it moves, a guide plate having an elongated opening formed there-- in for engagement with the shaft, the lower end or the latter being rotatably mounted in the opening formed in the outstanding lug, and means forming a part of said plate for securing the same rigidly to the float. I

2, In combination with u device of the character described, a plate having an elongated opening formed therein, a Host having an opening formed therein, an extension forming an integral part of said plate with its free end normally out of contact with the plate; whereby the plate together with its, extension is adapted to he forced into acorrespondingly shaped opening in the float and the plate held therein by frictional engagement, the elongated opening in the plate being adapted @to'engagea shaft for rotating the same and with the extension of the plate embracing the shaft of the device, whereby the float is prevented from rotating when the shaft is operated,

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
